Air source heat pumps across Ash Green

About our air source heat pumps in Ash Green

In England, an air source heat pump on a house can often go in under permitted development rights. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit cannot be used solely for cooling or sit within the curtilage of a listed building. We look at the planning position for your home during the survey. The work covers air-to-water heat pumps, homes heated by oil, LPG or gas and air-to-air heat pumps, and people most often call us about finding a place for the outdoor unit and wanting to stop using oil, LPG or gas for heating.

Space for an outdoor unit is rarely an issue near Ash Green, so the design focuses on heat loss and radiators.

Each manufacturer sets its own warranty period. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

What air source heat pumps cannot fix

Not every problem is solved by air source heat pumps, and we’d rather say so up front. It does not solve:

  • Getting planning permission or listed building consent on your behalf
  • Insulation work, such as loft or cavity wall insulation
  • Any gas work on the existing boiler

If in doubt, call us on 07833 053749 and we’ll say what we think before you book.

Parts of the system we cover

  • Underfloor heating
  • Air-to-water heat pumps
  • Air-to-air heat pumps
  • Radiator systems
  • Hot water cylinders
  • Homes heated by oil, LPG or gas

What we do, step by step

Each visit runs to the same pattern: agree the plan on site, put the dust sheets down, do the work, test what we’ve done and explain it all to you. On site, the work takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. For a village like Ash Green, tell us about narrow lanes, gates and parking when you book.

  1. First we talk through the property and the current system.
  2. Every room’s heat loss is worked out on site.
  3. The design covers the heat pump, emitters, hot water and outdoor unit.
  4. Cost, grant and VAT appear on one fixed-price quote.
  5. Then it’s fitted, commissioned and registered with MCS.

Getting ready for the visit

  • Let us know if the building has a permit or sign-in process
  • Tell us about parking and loading
  • Arrange for someone to be there to let us in

Questions from Ash Green

Can I get the Boiler Upgrade Scheme grant in Ash Green?

Yes, if the home and the heat pump meet the scheme’s rules: Ash Green is in England, where it applies. The amount depends on the type of heat pump, and the survey confirms which applies. You don’t apply yourself: the MCS certified installer does, which is us.

Can I fit a heat pump in Ash Green without planning permission?

There’s no single answer: the building and the outdoor unit position decide it. Historic England lists about 6 buildings and structures within half a mile of the centre of Ash Green. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask Guildford council, which is normally the planning authority for Ash Green.

How does the warranty work?

It’s the manufacturer’s, and the terms are theirs. Some terms depend on regular servicing by a qualified engineer, so keep your service records.

Will I get records for the system?

Yes. It’s the record a manufacturer or the next engineer will ask to see: the date, the work, and any refrigerant added or recovered.

What’s the difference between air-to-water and air-to-air heat pumps?

Air-to-water feeds your central heating and hot water, while air-to-air warms and cools rooms directly. Air-to-air does not heat hot water and the survey helps decide.

Do you work for landlords and businesses?

Yes. From a single let flat to offices, shops and public buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.

How much does an air source heat pump cost?

Expect £8,000–£16,000 for an air-to-water system, with 0% VAT on homes, before the grant is taken off. Where you land depends on the size of heat pump, any radiators that need changing and the hot water cylinder. Air-to-air is priced after a survey.

Leave it or put it right?

From 1 April 2027, VAT on heat pumps in homes rises from 0% to 5%. It’s a date to bear in mind when planning alongside your own plans for the property. Small faults tend to grow, so it’s worth dealing with them early.

The pipe route, the height of the units and how we reach them can all change the price. We take each of them into account and give you a fixed price before we start.

Different systems, different jobs

Air-to-water heat pumps

An air-to-water heat pump heats water for your radiators or underfloor heating and your hot water cylinder. It takes over from the boiler and we install it to MCS standards.

Outdoor unit position and planning

The outdoor unit needs a position with good airflow, a solid base and a sensible pipe route. Noise is part of the MCS 020(a) check, so we consider nearby homes too.

What a heat pump looks like in Ash Green

VOA council tax data date about 50% of homes across Ash Green and its surrounding area to the post-war years, 1945 to 1972, and the 2021 Census found about 61% of households in detached or semi-detached houses. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.

Wanborough Manor, roughly 2.1 miles east, is a reminder to check your home’s listing status: permitted development does not cover listed buildings. Live in one of the older houses around Church of St Peter? Expect the survey to look closely at heat loss and at the building’s planning status.
